function.hpp missing include guard patch

[nobody]

function.hpp does not have an #ifndef/#endif include guard.

This patch adds #ifndef BOOST_FUNCTION_HPP at the top
of the file and #endif at the bottom.

function.hpp isn't actually supposed to have include guards. The code it 
contains will never actually be included twice, but you can include 
function.hpp with BOOST_FUNCTION_MAX_ARGS set to different values to 
create support for greater numbers of arguments.
